Automotive car headlight two shot plastic injection molds

In case that you are quite new to two-shot plastic injection molding for Automotive industry, you might think it is more complex, more expensive, or more time consuming than other normal plastic molding processes. Taken alone, those may be true, but two-shot also creates considerable functionality and savings. Maybe you’ve been turned off by a manufacturer’s quality or delivery issues. We’re here to tell you that you deserve better. Whether you’re new to two shot or needing a new two-shot supplier, Zhejiang Ceeto Mold for Two-Shot Injection Molding is here to help you to know more about it. Because two-shot is all we do as usual.

There are two phases of the two-shot molding process during plastic injection molding. The first is similar to traditional injection molding: A shot of resin is injected into a mold and cooled to form a solid part. In the second phase, the just-molded part is transferred to a second mold via a rotating platen or a robotic arm, and receives the second shot of resin – in, through or around certain parts of the first molded part, depending on the design.

The two plastic resins then form a molecular bond and the multi-resin molded part is cooled and ejected.The process isn’t difficult to understand, but it’s highly difficult to master. It requires high levels of technical expertise and attention to detail, and even the smallest mistakes can cost big money, especially in high-volume production scenarios.
